Function does not return object in javascript

Question

I am returning an object in function but it returns undefined why? here is my code

parseXML = function (xml) {
        return {
            lon  : $(xml).find('GEOCODE').find("LOC").attr('lon'),
            lat  : $(xml).find('GEOCODE').find("LOC").attr('lat'),
            x    : $(xml).find('GEOCODE').find("LOC").attr('x'),
            y    : $(xml).find('GEOCODE').find("LOC").attr('y')
        };
    },

    searchRoute = function () {
        var userloc, dest; 
        userloc = cityattr.init(from, to, fromurl, parseXML);
        //dest    = cityattr.init(from, to, fromurl, parseXML);

        console.log(userloc);
    };

Update

When I do console.log() inside parseXML then it returns correct object

parseXML = function (xml) {
        var obj = {
            lon  : $(xml).find('GEOCODE').find("LOC").attr('lon'),
            lat  : $(xml).find('GEOCODE').find("LOC").attr('lat'),
            x    : $(xml).find('GEOCODE').find("LOC").attr('x'),
            y    : $(xml).find('GEOCODE').find("LOC").attr('y')
        };

        console.log(obj);
    },

Update 2

still return undefined

parseXML = function (xml) {
        return {
            lon  : $(xml).find('GEOCODE').find("LOC").attr('lon'),
            lat  : $(xml).find('GEOCODE').find("LOC").attr('lat'),
            x    : $(xml).find('GEOCODE').find("LOC").attr('x'),
            y    : $(xml).find('GEOCODE').find("LOC").attr('y')
        };
    },

here is code for cityattr

var Xml = function () {
var to, from, url, result,

    init = function (fromaddress, toaddress, link, callback) {
        from    = fromaddress;
        to      = toaddress;
        url     = link;

        requestXml(callback);
    },

    requestXml = function (callback) {
        $.ajax({
            type: "GET",
            url: url,
            dataType: "xml",
            success: callback
        });
    },

    getResult = function () {
        return result;
    };

 return {
    init        : init,
    getResult   : getResult
 };
};

You define the function using a function expression (so it isn't hoisted) after you pass parseXML to cityattr.init.

At the time you pass it, it hasn't yet been defined.

Change the order of your code or use a function declaration.

OP probably wants to call the function as well

Quentin Over a year ago

Possibly. Without knowing what cityattr.init does, it is hard to say. It might be expecting a callback function.

Well I changed the order but still it returns undefined

John Dvorak Over a year ago

Judging from "I am returning an object in function but it returns undefined", OP seems to think the function is being called

@JanDvorak What to do now? I think I am already calling a function which is parseXML
